In response to the new crown pneumonia epidemic in Jilin Province, China, the Provincial Department of Agriculture and Rural Affairs has activated an emergency mechanism to ensure a steady supply of vegetables. This involves converting large-scale shed films into emergency support bases for vegetable production and guiding farmers to grow fast-growing leafy vegetables. The department has also urged shed film parks to prioritize member orders to ensure the supply of vegetables to the community. Additionally, the department is providing remote consultation services to farmers through the "Double Hundred Joint Construction" campaign, and has launched an online 'cloud classroom' for farmers to improve production techniques. The results show a notable increase in the growth and development of crops in Jilin Province, with a higher vegetable planting area and harvest compared to the previous year.
